Does anyone know which advertising companies in Hainan province do light box advertising?

All advertising companies can do light box advertising, which is the business of the media department of the advertising company. However, this light box depends on how fast you do it. Different media are responsible for different light boxes in different places. You'd better go to the media to inquire about the price first, and then find an advertising company, so that you can be sure. However, the general advertising companies rarely increase the price when they put it in. In fact, what they earn is the rebate given by the media.

If you have money, find a better advertising company to help you build your brand well. If you don't have money, decide that the strategy is to find a few light boxes, then you can talk to the media who make light boxes directly.
